Recognize Only White Listed Characters & New API for Viewing Filtered Images

What’s new in this release?

We are pleased to announce the release of Aspose.OCR for Java 2.2.0. Aspose.OCR for Java API has exposed the Whitelist property for the OcrConfig class in order to provide the feature of Character White Listing. Now the developers can add a list of characters for recognition purposes. When Whitelist property is not null or empty, the OcrEngine recognizes only the specified characters while skipping everything else on the input image. The list of characters can be added to the OcrConfig class using its Whitelist property to enable this feature. Aspose.OCR for Java API has now exposed the PreprocessedImages class that allows the users to see how original input image is transformed during the OCR pre-processing steps.PreprocessedImages class has some useful properties that can retrieve the image at any particular stage of the OCR pre-processing.  Aspose.OCR for Java API allows to extract the text either as a whole or by parts whereas each part has its own Style, Font, Text Size and Location in the image, and all of this information can easily be extracted using the IRecognizedPartInfo and IRecognizedTextPartInfo class. The API also allows retrieving the hierarchy of each recognized part on the image as TextBlock, Line, Word or Character. Hierarchy of the recognized part can be extracted using the TextPartLevel class that has been exposed to the public API with this release. The IRecognizedTextPartInfo class has two useful properties such as Level and Children that provides the access to the hierarchical level and lower level textual parts respectively. This release includes plenty of new & enhanced features as listed below
